Cabin Air

Why do people need cabin air filters?

Think of them as an air filter that cleans air before it enters the cab's interior through the heating, air conditioning or fresh air systems. The filters remove allergens and pollutants before they get into the cab and before the driver and passengers can inhale them. Roadside air contains significant numbers of contaminants such as pollen, dust, diesel soot, and smog, and the contaminants are two to six times more concentrated inside the cab than outside.

Does the filter help allergy sufferers?

Yes. The filter traps virtually all pollen and dust particles that may cause allergic reactions. Such particles are generally 7 to 100 microns in diameter. A dot made with a sharp pencil is huge at 200 microns. The filters greatly reduce the amount of dust and pollutants entering the cab, so inside glass, dashboards, heating, ventilating and air conditioning systems do tend to stay cleaner.

How does the filter work?

Filter fibers are electro statically charged, allowing the filter to work at higher efficiency because it attracts and holds contaminants within the media. This reduces the chance of surface clogging and allows the filter to last longer. The filter screens out virtually all particles two microns in diameter and larger. A human hair is between 80 and 100 microns in diameter, so many of these particles are invisible to the naked eye. Like any other filter, Luber-finer cabin air filters need to be changed at routine intervals, following the vehicle manufacturer's recommendation.

What happens if the filter is not changed?

Air will still flow into the passenger cabin through the heating, air conditioning and fresh air systems. Once the filter media is saturated with contaminants, however, the pollutants and allergens may start entering the passenger cabin as well.

How effective are Luber-finer cabin air filters?

Luber-finer heavy-duty cabin air filters meet, and more often exceed, original equipment requirements for fit, function and performance. These filters are extremely efficient. They remove up to 99.5% of allergen contaminants from outside air.
